Description

A flaw was found in the kernel component, specifically within the drbd module. A local attacker could exploit a use-after-free vulnerability in the get_initial_state function. This occurs when a socket buffer (skb) object is prematurely freed, but the program attempts to use it later. Successful exploitation could lead to a system crash, information disclosure, or potentially arbitrary code execution.
